[PATCH] scsi: ufs: Wrap Universal Flash Storage drivers in SCSI_UFSHCD

[Geert Uytterhoeven <geert@linux-m68k.org>]

The build only descends into drivers/scsi/ufs/ if SCSI_UFSHCD is
enabled.  Hence all later config symbols should depend on SCSI_UFSHCD,
to prevent asking the user about config symbols for driver code that
won't be build anyway.  Unfortunately not all symbols have that
dependency.

Fix this by wrapping them all into a big if/endif block.  Remove the now
superfluous explicit dependencies on SCSI_UFSHCD from all symbols that
already had it.
